Answer:
p_k=\sqrt{p_x^2+p_y^2}}
Explanation:
Apply the momentum in each direction knowing that the impact is at the same time for the pieces so
So the momentum in the other piece can be find knowing that
So:
To find the velocity knowing the mass
Answer:
The political actions that led to successful conservation in both stories were what they call an FC company that makes the forest industry true. They make it out of a factory and it can make it very successful and accomplished.
Explanation:
Answer: Recall that
Work (W) = - e × ∆V
Where
Charge of electron= 1.6 × 10^ -19 c
And from the question we were given change in potential as = -0.0677V
Work = - (1.6 × 10^-19) × (-0.0677)
Work= 1.0832 × 10^-20J
Therefore the work done by the electric force when a sodium ion (charge = +e) moves from the outside to the inside is 1.0832×10^-20
The correct answer is Democritus
Explanation:
Momentum before collision:
(2 kg) (4 m/s) + (5 kg) (-3 m/s) = -3 kg m/s
No external forces act on the balls, so momentum is conserved. Therefore, momentum after collision is also -3 kg m/s.
